Fantastic!
I don't know what magic this pen has - but, it certainly lives up to all the hype. It's really easy to use and makes your face really smooth out and has a luminescent effect.
I recommend it highly.

A must have in my makebag!
I absolutely love the Yves Saint Laurent Touche Eclat highlighter. I use it everyday. I have used many concealers and have thrown out most of them. This is the first time I have used and continually reordered such an item. First of all, I was quite skeptical. It is such a light formula. And I have really dark circles and problem skin, along with spider veins across my cheeks. So you can imagine how I was wondering if this would even work. So I applied it as I would any concealer the first time. I looked at it and thought...okay, it doesn't look like it has covered well. So then I applied my powder makeup and WOW. It not only covered my problem areas, it made my skin seem illuminated...glowing. It actually minimized my problems and enhanced my good features. So the next time I tried applying it to not only diminish my bad spots, but I started applying to highlight around my lips to make them look fuller, etc. This is like white out for the skin. I now carry one in my purse as well as in my makeup bag. The perfect product for the not so perfect face.

Radiant Touch Highlighter (Yves St Laurent)
Very nice product. Not just for dark circles under eyes coverage. I have used this product for many years, have tried others and still come back to this one. Nothing seems to do the job as well. Covers up and highlights, too.

Absolutely fabulous!!!!!! I consider it indispensible. Lasts all day long, even when I am really tired. I think I might like it in a small jar instead of the pen style, though so you can see how much you still have.

I ordered in 2005 and it's been wonderful as a quick tool in my purse...anytme! Can't do without! I've tried every concealer on market and it's great for dark under eye circles! One of my top 5 of all time!!
